SPECIFICATION forming part of Letters Patent No. 749,907, dated. January19, 1904.

Application filed. March 2, 1903. Serial No. 145,702. (N0 111011610 T0at whom it may concern:

Be it known that I, J AMES A. SHARP, a citizen of the United States,residing at Chicago, county of Cook, State of Illinois, have inventedcertain new and useful Improvements in Grain- Headers; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to that type of machine which sever the heads ofthe grain only, leaving the stalks standing, and known as headers. Thesemachines are carried by a truck comprising supporting-wheels, one ofwhich is a traction-wheel. A long tongue is connected to the truckbehind the axle, and the rear end of the tongue is upheld by asteering-wheel, which also supports a stand for the driver. The team ishitched to this tongue in rear of the supporting-wheels, and leverconnections extend from the platform, reel, and other parts of themachine to the drivers stand.

The present invention relates to means for supporting and handling thereel in these machines, the difliculty of doing which is oftenconsiderable, owing to the length of the reelshaft, the.weight of thereel structure, and the distance of the driver from the reel-supports. I

This mechanism was formerly illustrated, described, and claimed inapplication Serial No. 97 ,930, filed by me March 12, 1902, and theclaims herein are dividedout of that application.

The invention is fully illustrated in the accompanying drawings, whereinFigure 1 is a plan view of the entire machine. Fig. 2 is a stubble sideview of all except the tongue. Fig. 3 is a vertical section on the line3 8, Fig. 1. Fig. 4: is a stubble side view of the tongue,-showing thedrivers stand and seat and the operating-levers. Fig. 5 is a grain sideView of the same parts. Fig. 6 is a cross-sectional view on the line 66, Fig. 5, looking rearward. Fig. 7 is a detail side View of the reelsupporting and operating parts. Fig. 8 is a section on the line 8 8,Fig.

Although the invention now claimed relates only to the reel and itsoperating and supporting mechanism, the entire machine is illustratedand described herein, so as to render unnecessary any reference to theother application. 1 1

The machine-frame, carrying the platform and the elevator, compriseslongitudinal angleiron sills a, extending from one end of the machine tothe other along the front and rear lower corners. At the stubble end ofthe machine the elevator]; and its struts c are erected on these sills,and at various points along the length of the rear sill posts d areerected, by means of which the wind-board e and rockshafts or rods f f,which carry the reel, are supported.

The truck consists of atubular sleeve 9, in-

' closing a through-axle, which is supported at The tongue is attachedto the axle-sleeve near.

the drive-wheel k and is connected to it at a point near the grain-wheelby a diagonal brace Z. The sleeve 9 is connected to the tongue and braceby means of clips on n.

At the stubble end of the machine there is a gearing-frame 0, having oneof its arms suspended from the end of the axle outside the main wheeland the other end bolted to the under side of the axle-sleeve on thegrain side of the wheel. The frame 0 is rigidly connected at its rearend to the tongue .and carries the cOunter-shaftq, which is driven fromthe main wheel in the usual way.

Pivoted to the inner side bar of the gearframe in rear of the axle is aforwardly-projecting bar 1 that extends all the way acrosspivoted at apoint in rear of the axle instead of being pivoted on the axle, asheretofore. The bars rs'are rigidly secured to the base-sills a, and tofirmly brace and unite the machineframe to these bars 7 s diagonalbraces ta extend from the sill (Z to the bars 1 and .9, respectively,near their pivoted connection with the tongue and brace Z, and the wholestructure is further braced by a bar 0), extending from a point on theouterlside bar of the gearing-frame 0 to the upper end of theelevatorframe, and an adjustable tie-rod 10, extending from an arm a atthe outer side of the grainwheel to the upper end of the outermost post(Z.

The bars 9' and s and the entire machineframe, which is supportedthereby, are, as to their elevation from the ground, under the controlof the driver through the intermediacy of vertical posts a Z), that arepivoted at their lower ends on the axle-sleeve and are connected to thebars by adjustable pivoted rods 0 CZ. From the upper end of the postsrods 0' e extend rearward and connect with the upper end of a lever g,pivoted to a saddle h, bolted to the tongue. The lever g has an armextending below its pivot, where it is connected to the rear end of astrong coil-spring i, whose front end is connected at any convenientfixed point, so that the tension of the spring will counterbalance theframe and assist the driver in lifting it. Extending rearward from thecounterbalance-lever there is a rod 10, which leads to the upper arm ofa bell-crank Z, that is freely pivoted to the casting which carries thedrivers stand m. The lower end of the bell-crank has a coil-spring itconnected to it, the other end of the spring being connected to a fixedpoint on the tongue, so that this spring forms an additionalcounterbalance for the frame of the machine. The lever Z is free toswing forward and backward. It has no direct connection with the notched segment 0; but there is pivoted alongside of it and on the same axisa hand-lever j, which has the usual latch connection with the segment,and the upper end of the lever Z has a lateral projection that overlapsbehind the hand-lever. The hand-lever is normally locked to its segment,and therefore forms a a stop to limit the forward movement of the upperend of the lever Z; but the latter is free to move independently of thehand-lever behind it, and as the weight of the machine is carried by thesprings z" and n the lever Z and the lever g are floating levers in thenormal operation of the machine.

The lever Z is provided with a rearwardlyextending foot lever 12, bymeans of which the driver may raise the platform without operating thehand-lever; but whenever it is desired to lower the platform thehand-lever must be unlocked from the segment, and when so released thelever Z may be freely operated in either direction by the foot or bymeans of a spring-catch g on the hand-Iever hooking over a projection onthe lever Z, whereby the two levers are locked together and operate asone.

Referring now to Fig. 8, 0", s, and 6 dcnote sprocket -wheels aroundwhich an endless chain is thrown to drive the platform-carrier, thecutters, the lower elevator-aprons, and the binder when one is employed.these sprockets 'r is the driver, and it is driven by means of atumbling-shaft a, connected to a short shaft journaled in a boxing 7;,carried by the gearing-frame. The short shaft has a pinion w on its rearend that is driven by the bevel-gear a" on the outer end of thecountershaft 9. The upper apron of the elevator is driven by atumbling-shaft which connects at its front end to the shaft of theroller a and is connected to a short shaft journaled in the same boxingo. This shaft has a pinion Z), that meshes with the pinion a in one partwith pinion 20, so that the tumbler (Z2 is driven by pinion u, and bothare driven by the gear a" 0n the counter-shaft.

The support and operation of the reel is a difficult matter in thisclass of machines. In the present invention the vertical posts (Z, thatrise from the rear sill (Z of the platformframe, carry in bearings attheir upper ends a pair of parallel tubular rocking shafts, rods, orpipes ff", heretofore referred to, the inner ends of these shafts beingsupported in suitable hearings in a casting 0 that is securely fastenedto the apex of the elevatorframe and struts 0 0. These rocking shaftsform the means for operating the reel, one of them serving to lower andraise it and the other acting to throw it forward or backward withoutmaterially changing its elevation. The reel-shaft is supported on boxes0", that slide in and out on arms 0 at each end of the platform, whicharms are secured to castings that are sleeved on the rocking shaft f, asmore fully described later on, and are braced by tie-rods c, that extendfrom a point near their outer ends to the upper ends of brackets 0 Thesliding boxes 0 of the reel-shaft are connected by rods 0 with the upperends of arms 0, that are fixed to and project upwardly from the upperrocking shaft f at its opposite ends, and to a downwardly-projecting armd, that is secured to the shaft some distance stubbleward from the innerarm 0, is connected a rod d", running rearwardly to the drivers standand connected to a hand-lever 6 the rod on its way passing through aguide 6Z5, fixed on the tongue to prevent it from sagging and beingpreferably adjustably connected to the lever e by means of a perforatedsocket a", into any of the holes of which the hooked rear end of thelever may be set. The rocking of the upper shaft-pipe f by these meanscauses the boxes 0 to slide in or out on the arms a without altering theelevation of the arms, and the position of the reel is thus adjustedfore frame 0.

and aft as desired with respect to the line of the cutters. The lowerrocking shaft or pipe rod f is also journaled in bearings in theoutermost post (i and the casting 0 and at opposite ends it hasgear-segments d fixed on it, that intermesh with similar segments (Zthat are loosely journaled on the upper rod f. The reel-supporting arms0 before described, are bolted to the castings on which these loosesegments d are formed, so that on rocking the lower rod or shaft f bymeans of the depending arm d, which is fixed thereto, the castingscarrying the upper segments d and the reelsupporting arms 0 will berotated around the rod f and the vertical height of the reel will bealtered. A rod (Z leads from the lever (Z backward to a hand-lever d onthe drivers stand, by means of which the height of the reel iscontrolled, this rod also passing through the guide 03 on its way. Theweight of the reel is counterbalanced by means of a coilspring 9, thatis connected at its front end to a fixed point under the tongue and hasits rear end connected to a depending extension g of the lever 623*,that raises and lowers the reel and puts the Whole reel structure underthe quick and easy control of the driver. The reel is driven from asprocket-wheel e on the axle outside the main wheel, an endless chain 6on this sprocket passing around a similar wheel on the end of thereel-shaft and passing on its way over and around the sheaves e of aspringheld compensating tightener e The drivers stand m is formed on acasting that is bolted to the rear end of the tongue, and in a bearing 6in this casting the vertical stem of the yoke 6 which carries thecasterwheel, is journalecl. The ratchet-segments for the several leversalready described are fixed on the stand-casting, and the leversthemselves are also pivoted thereon. A foot-lever f is also pivoted onthe stand, and a rod f runs from said lever to a clutch f on thegearing- By this means the counter-shaft may be unclutched from thepinion 0 and the movement of all the operative parts may be instantlystopped.

The constructions being as thus described it is to be noted that thearrangement for supmeans of bolts 9 and g the latter securing the armspivotally to the flange g of the segments and the former passing throughthe rear ends of the arms and through lugs g that project from the rearsides of the castings, thereby providing for an adjustment around thepivot in the range of up-anddown movement of the reel in addition tothat obtained by the hand-operating lever.

Having thus described my invention, what I claim is 1. In a header, thecombination of posts rising from the rear part of the platform, a shaftor rod carried by the posts, reel-supporting arms sleeved on oppositeends of said shaft, a rockshaft or rod carried by the posts, gears atopposite ends of said rock-shaft and meshing with gears rigid with thereel-supporting arms, a lever within the drivers reach, and a connectionfrom the lever to the rock-shaft.
